Do tall doors fit a "normal" room height?

it often needs one more step and therefore more space.

Or not, but it becomes steeper. The "wobble" with a few centimeters more or less ceiling height, I would not put the focus on it. So that a floor plan stands or falls with one step surface more or less should not be planned.

This is one of those points where you have to say, important? - actually yes - considered on its own; but half a dozen of these kinds of details and the amateur planner surrenders ;-)

And ultimately, the ceiling height is also a product of the overall structure. Normally, we would have had about 2.5x m clear ceiling height. However, due to the under-slab insulation but less insulation on the slab, the floor construction on the slab is reduced and the ceiling height increases. There are also half-height bricks, but the shell builder prefers to build everything from the same brick to reduce waste, and so either a full brick height is used or not, he will not halve a brick for a complete row.

There are also half-high stones, but the shell builder prefers to build everything out of the same stone to reduce waste, and so either a full stone height is used or not; he will not halve a stone for a complete row.

There are also height compensation bricks, and by the way also DF, NF, and 2DF, which alone can avoid waste through their formats and can practically produce exact desired floor heights to within 2 cm.

Since we are planning the house as a timber frame, we definitely need to determine the ceiling height before the house goes into production :)

Currently, we use a standard height of 2.50 m. I know this from our current apartment, I know it from my parents' house - from our point of view absolutely sufficient.

Thanks already for the feedback!

One is used to many things from the past, that doesn’t mean it can’t be done better. We previously also only had 2.50 m room height and normal doors, of course it worked... but now with higher doors and higher ceilings it is 1000 times nicer. I would reconsider that carefully.

There are also height compensation bricks, and incidentally also DF, NF and 2DF, which by their formats alone can avoid offcuts and can effectively be manufactured to desired story heights with an accuracy of 2 cm.

I am aware of that, but it is not worthwhile for the shell builder, because in the end he always has some leftover expensive special formats. Therefore, he prefers only standard formats, calculated tightly; if that is not enough, he has some on the yard. He also has a saw anyway. What I mean is, a complete layer of half bricks will be much more expensive for him than a layer of normal bricks.

But since this is timber frame construction, it does not matter here anyway.
